Bernard Green weighed 427 pounds when he died in 2004. He was 43 years old.

"He didn't have to die," said Green-Jackson. "I promised myself that I would do whatever I could to make sure another child didn't suffer like he did."

Turning her pain into action, Green-Jackson quit her job and procured $30,000 in grants to build a fitness center in a local middle school.

Today, Youth Becoming Healthy (YBH) has facilities in six middle schools and one elementary school in Albany and provides free fitness and nutrition education to about 350 students a year.

Youths work one-on-one after school with personal trainers and nutritionists who help them get on the right track. To keep young people engaged and fit, YBH offers classes such as martial arts, hip-hop dance and a walking club. Green-Jackson says her group allows the children to set their own goals.

"One in three children in this community is affected by childhood obesity because of poverty, lack of education and access to resources," said Green-Jackson, adding that dangerous neighborhoods are also a major obstacle.

"Kids don't go out and play as much anymore because of the gangs and the crime. It is unsafe."

Georgia has the third-highest rate of obese and overweight youths in the nation, with 37.3 percent of its children falling into those categories, according to a recent report from the Trust for America's Health and the Robert Wood Johnson Foundation. (Mississippi and Arkansas rank one and two, respectively.)

This summer, the group is offering camp for students with high-risk health issues, such as heart problems, kidney disease, high blood pressure and high cholesterol.

"A number of kids have [these issues]. That is unheard of," said Green-Jackson. "These children are [given] prognoses that they won't live to 21 years old. That is something we are trying to correct through this program."

At nearly 400 pounds, every day is a struggle for 13-year-old Malik Thomas.

"It's not easy carrying around all of this weight. I wanted to get healthy and fit," said Thomas, one of 25 children enrolled in YBH's summer program.

Green-Jackson's program is giving Thomas hope for a healthier future. He's beginning to lose weight, and his endurance has improved.

Green-Jackson believes the program will help Thomas by introducing him to other young people who share his health problems.

"They motivate each other," she said. "This program is encouraging him to continue beyond the summer."

YBH is mostly funded through donations, but Green-Jackson also spends a large amount of her own savings each year to keep the program running. She says she refuses to rest until the children's healthy futures are secured.
